Abstract

The invention provides a spine posterior device. The device comprises a device body and a connection part; the device body is arranged on the side, away from the vertebral body of the human body, of the spine, and is used for promoting bone ingrowth; the connection part is arranged on the device body and used for being connected with a posterior nail bar to fix the device body. According to the spine posterior device, the connection part is connected with the posterior nail bar, accordingly, the device body is positioned at the osteotomy portion, the position of the device body is equal to theposterior column part, the device body can promote bone ingrowth, bone healing of the posterior column part is promoted, finally the posterior column part of the spine is rebuilt, long-term stabilityis achieved, and the post-operation risk is lowered.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a posterior spinal device. Background technique [0002] The human spine will be damaged due to illness or external force, such as vertebral body tumors, severe comminuted fractures, and infectious diseases such as tuberculosis, which may lead to spinal cord and nerve damage or collapse of vertebral segments and angular deformity of the spine. Vertebrectomy is often required in patients with obvious neurological dysfunction or angular deformity. [0003] The stability of the human spine is determined by the structure of the spine. According to the three-column theory, it is distinguished from the anatomical shape of the spine. The anterior longitudinal ligament of the spine and the anterior 1 / 3 of the vertebrae are the anterior column of the spine, and the posterior 2 / 3 of the vertebrae is the anterior column of the spine. The posterior longitudinal ligament forms the middle c...
